Agrep is similar to the standard UNIX grep utility, but is more general, and according to its authors, usually faster. Its most notable feature is the approximate pattern matching facility. Agrep has other features not found in the grep family: It is record rather than line orientated; pattern matches can be output in a larger context than a single line. Multiple search patterns can be specified with AND/OR logic.Project Home: ftp://ftp.cs.arizona.edu/agrep/
